VEHICLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 721,002, dated February17, 1903.

To @Z whom, t may concern:

Beit known that I, J EAN BAPTISTE Boum- CAULT, a citizen of the UnitedStates, residing at St. Louis, State of Missouri, have invented 5certain new and useful Improvements in Vehicle-Wheels, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part hereof.

My invention has relation to improvements in vehicle-Wheels; and itconsists in the novel construction of wheel more fully set forth in thespecification and pointed out in the claim.

In the drawings, Figure l is an elevation of the wheel. Fig. 2 is amiddle vertical section of the Wheel, and Fig. 3 is an edge viewr ofthewheel.

The object of my invention is to construct a wheel for vehiclesgenerally which will insure easy travel over roads of any description,be the same smooth or rough, hard or soft..

It consists in details which vmay be described as follows:

Referring to the drawings, A represents the axle of the vehicle, be' thesame an ordinary wagon, carriage, or automobile, the invention not beingrestricted to any particular class of conveyances. The wheel is composedof two disks l l, pressed or formed so as to possess a maximum degree ofstiiness and at the same time present a neat appearance, said disksbeing united at convenient points by rivets 2 and connected to the hub Hby pins 3 passed through the flanges H of the hub, the disks beingfurther reinforced around. the hub by an annular channel-bar 5, throughthe sides of which are passed the rivets 4, coupling the same to thedisks. The outer or peripheral edges of the disks are spanned by the rim6, riveted to the respective disks, the rivets be- Application ledAugust l5, 1902. Serial No. 119,723. (No model.)

ing passed through the marginal flanges 7 of the disks and through thebases of the diagonally-dispcsed channel plates or shoes S. The latterare disposed peripherally about the central groove or depression 9 ofthe rim 6, the axes of the shoes being inclined to the plane of rotationof the Wheel and their purpose being to plow or cut their way throughsoft soil should the weight` of the vehicle cause the tire ll0 to becomeembedded in such soft earthor soil.

The tire is preferably made of rubber and is secured within the groove 9in any mechanical manner known in the art. It is apparent, of course,`that this form of wheel need not be limited in its application toordinary roads, for the principle of the shoes 8 can be made availablefor ice roads, snow, and the like.

Having described my claim is- A vehicle-wheel composed ofya pair ofdisks rotatable about an axle, and united at convenient points byrivets, an annular stiftening channel-bar surrounding the hub andsecured to the disks, a peripheral rim having a central depression,secured to the outer edges of the disks, a tire located Within saiddepression and extending a suitable distance beyond the peripheries ofthe disks, and a series of channel plates or shoes disposed on the rimon each side of the tire, and inclined to the plane of rotation of theWheel, substantially as set forth. In testimony whereof I aixmy'signature in presence of two witnesses. c
